Substitution and Stratification: The Interplay between Dyadic and Systemic Proximity in Global Trade, 1993–2005

This article examines the interplay of homophily (similarity breeds connection) at two levels in international trade—dyadic similarity (geographic, political, and cultural proximity) and systemic similarity (structural equivalence and world‐system status). First, there is a substitution effect between dyadic homophily and systemic homophily from structural equivalence. Both types of homophily generate favorable social structure that facilitates international trade. The existence of structural equivalence lessens the dependence of bilateral trade on dyadic homophily. Second, there is a stratification effect of world‐system status on dyadic homophily. Geographic homophily matters the most for bilateral trade between two noncore countries, while political and cultural homophily is the most influential for trade between a core country and a noncore country. These two findings have important implications. The substitution effect of structural equivalence prevents international trade from complete fragmentation along geographic, political, and cultural lines, while the stratification effect of world‐system status reveals unequal capacity across countries to overcome the structural constraints imposed by dyadic homophily.

社会风尚变迁影响下的《陌上桑》之流变——以明朝《陌上桑》拟作为中心

《陌上桑》是乐府民歌中的精品。后世许多文人雅士以相同的题目,或以其中的女主人公罗敷为题材,写出内容相近的诗作,被称为《陌上桑》的"拟作"。从汉代以后,直到清代,"拟作"不断,其风格深受诗作者所处时代的社会风尚的影响。唐前及唐代的"拟作"唯美而浪漫;宋朝至明朝中叶之前的庄重;明朝中叶之后再现浪漫。同情蚕农疾苦和表现真善美则是《陌上桑》"拟作"之永恒的主题。

论新形势下乡镇政府职能的转换

我国乡镇政府工作和乡镇政府职能面临着许多新问题。因此,提出乡镇政府职能要由全能的"无限责任政府"转变为"有限责任政府"、要由忙于应付的"任务型政府"转变为"公共服务政府"、要由错位的"权责脱节型政府"转变为"权责对等型政府"的转换路径,并从行政体制改革、组织设置、队伍建设、财政改革以及社会中介组织培育等方面提出了推动乡镇政府职能转换的具体措施。     

走向对话与支持的教育共同体

诸多教育问题的产生源于两个主要问题:其一是学校教育的功能有限性;其二是教育主体之间的教育价值冲突。因而,我们需要重新定位学校教育的有限功能,并寻求教育主体之间能够达成共识的教育价值观。本文认为,建立在公共利益基础上的教育价值共识是解决教育问题的思想基础;以这种教育价值共识为基础,借助于信息技术支持的交流、交往、传播功能,建设多主体、多渠道、多层次的对话平台,以相互支持为准则的教育共同体是解决教育问题的实践路径。

Quantitative and qualitative examination of propositions concerning supervisor–subordinate convergence in descriptions of leader–member exchange (LMX) quality

Two studies were conducted to quantitatively and qualitatively examine supervisor–subordinate differences in perceptions concerning the quality of their LMX relationship. The results provided strong support for a lack of construct convergence between these two perspectives. Specifically, the findings suggest that leaders tend to focus more on task-oriented subdimensions and tend to give them greater weight when evaluating LMX relationships. However, subordinates are more oriented toward the social aspects of the relationship and perceive them as more important. This differential pattern was found to be generalizable across gender, race, and industry types.     

Estimating survival curves with left truncated and interval censored data via the ems algorithm

It is well-known that the nonparametric maximum likelihood estimator (NPMLE) of a survival function may severely underestimate the survival probabilities at very early times for left truncated data. This problem might be overcome by instead computing a smoothed nonparametric estimator (SNE) via the EMS algorithm. The close connection between the SNE and the maximum penalized likelihood estimator is also established. Extensive Monte Carlo simulations demonstrate the superior performance of the SNE over that of the NPMLE, in terms of either bias or variance, even for moderately large Samples. The methodology is illustrated with an application to the Massachusetts Health Care Panel Study dataset to estimate the probability of being functionally independent for non-poor male and female groups rcspectively.
